Ta yaya LED ke samar da haske?

Electroluminescence shine tsarin da LEDs (Light Emitting Diodes) ke samar da haske. Ga yadda take aiki:

1-Semiconductor Material: Kayan semiconductor, yawanci cakuda abubuwa kamar phosphorous, arsenic, ko gallium, ana amfani dashi don yin LED. Dukansu yanki na n-type (mara kyau), wanda ke da wuce gona da iri na electrons, da kuma nau'in p-type (positive), wanda ke da ƙarancin electrons (ramuka), ana samar da su ne lokacin da semiconductor ya cika da ƙazanta.

2-Electron-Hole Recombination: Electrons daga yankin n-type ana tilasta su zuwa yankin p-type lokacin da aka sanya wutar lantarki a fadin LED. Wadannan electrons suna sake haɗuwa tare da ramuka a cikin nau'in p-type.

3-Emishin Hoto: Ana fitar da makamashi azaman haske (hotuna) yayin wannan aikin sake haɗawa. Ƙarfafa ƙarfin ƙarfin abu na semiconductor da aka yi amfani da shi yana ƙayyade launin hasken da aka saki. Haske yana zuwa cikin launuka iri-iri dangane da kayan.

4-Yin aiki: Tun da yawancin makamashi a cikin LEDs an canza su zuwa haske maimakon zafi-matsalar gama gari tare da kwararan fitila na al'ada-LEDs suna da inganci sosai.

5-Encapsulation: Ta hanyar lulluɓe LED a cikin madaidaicin guduro ko ruwan tabarau, hasken da yake fitarwa yana haɓaka akai-akai. Wannan kuma na iya taimakawa wajen yaɗa hasken da sa ya yi kyau.

Idan aka kwatanta da hanyoyin walƙiya na al'ada, wannan tsarin yana ba da damar LEDs don samar da haske mai ƙarfi, mai da hankali yayin amfani da ƙarancin kuzari.

Duk da tsayin daka da ingancin su, fitilun LED na iya samun wasu al'amura na yau da kullun, kamar:
1) Bambancin Yanayin Launi: Rashin daidaituwar hasken wuta a cikin yanki na iya haifar da canjin zafin launi tsakanin batches na fitilun LED.

2) Flickering: Lokacin amfani da maɓallan dimmer marasa jituwa ko kuma lokacin da akwai matsaloli tare da wutar lantarki, wasu fitilun LED na iya yin kyalli.

3) Yawan zafi: LEDs suna samar da ƙarancin zafi fiye da fitilu na al'ada, amma rashin isasshen zafi na iya haifar da zafi, wanda zai iya rage tsawon rayuwar kwararan fitila.

4) Matsalolin Direba: Don sarrafa iko, fitilun LED suna buƙatar direbobi. Hasken na iya lumshewa, dushewa, ko daina aiki gaba ɗaya idan direban ya yi kuskure ko kuma ba shi da inganci.

5) Daidaituwar Dimming: Matsalolin ayyuka na iya tasowa saboda wasu fitilun LED ba su dace da masu sauyawa dimmer na yanzu ba.

6) Iyaka kusurwa mai iyaka: Lightven haske na iya haifar da hasken wutar lantarki tare da kusurwa mai iyaka, wanda bazai yuwu ga aikace-aikace da yawa ba.

7) Farashin farko: Kodayake fitilun LED suna adana kuɗi akan lokaci, suna iya kashe kuɗi don siyan farko fiye da kwararan fitila na al'ada.

8) Damuwa na Muhalli: Idan ba a zubar da shi yadda ya kamata ba, gano matakan abubuwa masu haɗari kamar gubar ko arsenic da aka samu a wasu fitilun LED na iya yin haɗari ga muhalli.

9) Bambance-bambance a cikin inganci: Akwai samfuran LED daban-daban a kasuwa, kuma ba duka ana kera su zuwa ma'auni iri ɗaya ba, wanda ke haifar da bambancin rayuwa da aiki.

10) Rashin daidaituwa tare da Wasu Fixtures: Wasu kwararan fitila na LED, musamman waɗanda aka yi don kwararan fitila na al'ada, ba za su iya aiki da kyau a cikin takamaiman kayan aiki ba.

Zaɓin abubuwa masu inganci, tabbatar da cewa suna aiki tare da tsarin yanzu, kuma bisa ga umarnin shigarwa akai-akai don warware waɗannan matsalolin.

Akwai fitilun haske da yawa da za a zaɓa daga kasuwa yanzu, kamarFarashin COBCSP tsiri, daban-daban daFarashin SMD, tuntube mu idan kuna buƙatar samfurori don gwaji.
